Patience and attention to detail are crucial for top-shelf cannabis. Each step impacts your buds’ final quality.

1. When to Harvest

Timing your cannabis harvest is crucial. Focus on trichomes and pistils:

Trichome Method:

Use a jeweler’s loupe or USB microscope. Look for:

Trichome Color	Meaning	Effect
Clear	Not ready	Low potency
Milky white	Peak potency	Strongest effects
Amber	THC degrading	More body high

Aim for mostly milky white trichomes with about 10% amber.

Pistil Method:

Harvest when 60-70% of pistils have turned brown or orange.

Strain-Specific Timing:

Different strains have varying harvest times. For example, Chiquita Banana: Harvest after 56 days of flowering for a clear high, or wait an extra week for a more relaxing effect.

"The harvest time depends mostly on marijuana strains and phenotypes, and can vary from several days to a few weeks between different cannabis varieties." – Robert C. Clarke, "Marijuana Botany" author

Harvesting too early can result in lower THC and poor taste, while harvesting too late may lead to loss of essential oils and cannabinoids.

2. Flushing Before Harvest

Flushing removes excess nutrients from your plants before harvest. It can improve flavor, reduce harshness, and enhance potency.

When to Start Flushing

Soil: 2 weeks before harvest
Coco coir: 1 week before harvest
Hydroponics: 1-2 days before harvest

How to Flush

Stop using nutrients
Water with pH-balanced plain water (6.0-6.8 pH for soil)
Flood the growing medium and let it drain
Repeat after 15 minutes

Monitoring Progress

Use a TDS meter to check runoff water:

Start: Around 1300 ppm
Goal: Below 50 ppm

Some yellowing of leaves is normal during flushing.

Flushing Debate

Not all growers agree on flushing. Some find it unnecessary, especially for organic grows. Others swear by it for quality improvement.

"I personally did not like it for it DEFINITELY reduced the smell of the product." – Anonymous Grower

Consider your goals and growing methods when deciding whether to flush.

3. Controlling the Harvest Environment

Managing temperature and humidity during harvest is key for quality buds.

Temperature Control

Keep your drying room between 60°F and 70°F (15.6°C to 21°C).

Humidity Management

First 2-3 days: 70% relative humidity (RH)
By end of week: Below 60% RH
Final target: 55% RH

Use a hygrometer to monitor humidity levels.

Air Circulation

Use fans for air circulation, but avoid blowing directly on buds.

Light Control

Keep the drying room dark to preserve cannabinoids and terpenes.

Equipment Recommendations

Equipment	Purpose
Dehumidifier	Reduce humidity
Air conditioner	Control temperature
Oscillating fans	Ensure air circulation
Hygrometer	Monitor humidity levels

"I like 60F / 60% RH… faster dry is harsher smoke, and too slow risks mold."

Drying typically takes 10-14 days. Buds should feel slightly crunchy when squeezed, and smaller stems should snap when bent.

4. How to Cut Cannabis Plants

Cutting cannabis plants properly is crucial for a successful harvest.

Prepare Your Tools

Sharp, clean scissors or pruning shears
Powder-free nitrile gloves
Large plastic tray or tub
Twine or string for hanging

Timing Is Everything

Cut plants early in the morning or soon after lights come on for indoor grows.

The Cutting Process

Put on gloves
Cut main stem at base for small plants, or individual branches for larger ones
Place cut branches gently on plastic tray
Remove large fan leaves

Hanging Your Harvest

Tie branches with twine near the cut point for easy hanging and better air circulation.

Pro Tip: Leave a small "popcorn bud" on the four lowest branches if you plan to regrow.

Cutting Method	Pros	Cons
Whole Plant	Faster, easier	Less air circulation
Branch by Branch	Better air circulation	More time-consuming

"When you take extra care during and after the critical harvesting stage, this can preserve the potency, flavour, and effect of your weed much better." – Miguel Antonio Ordoñez, Writer

5. Wet vs. Dry Trimming

Choosing between wet and dry trimming impacts your final product quality and production efficiency.

Wet Trimming

Pruning cannabis buds right after harvesting, while still moist.

Dry Trimming

Allowing harvested plants to dry before trimming.

Comparison:

Aspect	Wet Trimming	Dry Trimming
Speed	Faster	Slower
Space Required	Less	More
Risk of Mold	Lower	Higher
Terpene Preservation	Lower	Higher
Bud Density	Lower	Higher
Ease of Trimming	Easier	More difficult
Visual Appeal	Cleaner appearance	More natural look
Trichome Preservation	Better	Can be damaged during drying

Industry Insights

"We found the GreenBroz trimmer, and it’s a dry trimmer which is very important to us. Wet trimming damages the flower and causes bacterial infection to happen and it also causes terpene loss." – Dr. Jade Stefano, CEO of Puffin Farms

"Wet trimming is easier. It is easier to remove the fan and sugar leaves while they are wet." – Christopher Wicklander, Cannabis Industry Expert

Choose based on your priorities: simplicity and reduced mold risk (wet trimming) or top-quality buds (dry trimming).

6. Drying Cannabis Slowly

Slow drying preserves quality, potency, and flavor of your buds.

Ideal drying environment:

Temperature: 60-70°F (15-21°C)
Relative humidity: 45-55%
Dark room
Good air circulation

Why these conditions matter:

Factor	Impact
Temperature	Too high: Degrades cannabinoids and terpenes Too low: Slows drying, risking mold
Humidity	Too high: Mold risk Too low: Over-drying, harsh smoke
Light	Degrades THC
Air circulation	Prevents mold, ensures even drying

Drying typically takes 7-14 days. Rushing can lead to harsh smoke, potency loss, and mold growth.

How to dry cannabis properly:

Set up drying space
Hang plants upside down or use drying racks
Monitor daily
Test for dryness using stem snap test

"Removing moisture helps to tone down the harshness and let the terpene profile shine." – RQS Blog

After drying, buds typically have 10-15% moisture content. Curing further improves quality and extends shelf life.

7. Curing Cannabis

Curing enhances quality, flavor, and potency of your harvest.

Benefits of curing:

Improves flavor and aroma
Increases smoothness of smoke
Preserves cannabinoids and terpenes
Extends shelf life (up to 2 years)
Reduces mold risk

Curing process:

Prepare buds: Trim and place in airtight glass jars, filling 75%
Control environment: Store in dark place at 60-70°F (15-21°C), 55-65% humidity
Burp jars: Open daily for first week
Monitor and adjust: Check for mold, track humidity
Be patient: Cure for 2-8 weeks

Curing Duration	Expected Results
2-4 weeks	Basic improvement in flavor and aroma
4-8 weeks	Enhanced flavor, aroma, and smoothness
2+ months	Maximum potential reached (for some strains)

"Curing is like aging a fine wine. It takes time, but the results are worth it." – Jorge Cervantes, cannabis cultivation expert

Use Boveda packs or similar products to maintain ideal moisture levels during curing.

8. Harvesting for Concentrates

Harvesting for concentrates requires a different approach to maximize trichome retention and preserve volatile compounds.

Key steps:

Harvest at dawn for more terpenes
Handle with care to reduce trichome loss
Use Fresh Frozen method: remove leaves/branches, package wet buds, freeze at -40°F (-40°C)
Choose high-THC, resinous strains for better yields

Strain	Characteristics	Extraction Method
Sour Tangie	High THC, lots of resin	Rosin extraction
Lemon Jah Goo	High THC, lots of resin	Rosin extraction

Assess trichomes for best extraction method
Prepare for specific extraction methods (ethanol, CO2, hydrocarbon)

"Ethanol extraction offers higher throughput compared to CO2 and hydrocarbon systems; it’s perfect for making distillates and isolates at scale." – Jim Moore, VP of New Product Development at Prospiant

9. Harvesting in Stages

Staged harvesting can boost yield and bud quality.

Benefits:

Addresses uneven ripening
Increases yield
Allows for tailored effects

How to do it:

Harvest top buds when 50% of pistils have turned red/brown
Monitor trichomes:
- Clear: Not ready
- Milky white: Peak THC (energetic high)
- Amber: More CBN (sedative effect)
Wait 1-2 weeks for lower buds to mature
Use clean, sharp tools

Trichome Color	Effect	Harvest Time
Milky White	Energetic High	90% milky, 10% amber
Amber	Sedative Effect	50-70% amber

"The harvesting period, followed by the drying and curing stage, is so crucial and unfortunately, is where a lot of mistakes are made", – Evan Marder, Cannabis Community College Professor of Cultivation

10. Checking Quality After Harvest

Ensure top-notch quality post-harvest:

Visual Inspection: Use a jeweler’s loupe to check for dense trichomes, vibrant colors, and no mold
Moisture Content: Buds should be slightly sticky, spongy, with easily snapping stems
Aroma Test: High-quality cannabis has a fresh, distinct smell
Lab Testing (for commercial growers):

Test Type	What It Measures	Why It’s Important
Potency	THC, CBD levels	Ensures consistent labeling
Contaminants	Pesticides, heavy metals	Guarantees consumer safety
Microbial	Harmful microorganisms	Prevents health risks

Storage: Use airtight glass containers in a cool, dark place

"If it don’t smell like weed, don’t smoke it." – Crutch 420, Cannabis Enthusiast

Regular checks and proper storage help preserve potency and safety.
